____________ is translated by the ribosomes and contains the code that specifies the sequence of amino acids in a polypeptide ch

HACTEHA [7]

mRNA (Messenger RNA) is translated by ribosomes and contains the code that specifies the sequence of amino acids in polypeptide chain.

A single-stranded ribonucleic acid molecule is known as messenger RNA(mRNA) plays a major role in translation.

Translation is the method by which an mRNA codes for a certain protein. mRNA provides the template for protein synthesis.

The ribosome translates the mRNA that is produced from the DNA into a chain of certain amino acids and protein synthesis is facilitated by this amino acid sequence.

The genetic code, which connects the DNA sequence to the amino acid sequence of proteins, is used to "read" the mRNA. Each group of three nucleotides in mRNA forms a codon, and each codon corresponds to a particular amino acid (triplet code).

Thus mRNA contains the code that specifies the sequence of amino acids in a polypeptide chain.

Freshwater is defined as having a low _______ concentration, usually less than 1%.

vampirchik [111]

Answer: salt

Freshwater is defined as having a low salt concentration, usually less than 1%.

Explanation:

Freshwater refers to the bodies of water that contain very low levels of dissolved salts. So, freshwater are unique for their low salt content (about 0.5% of salt) compared to the sea water with high salt content.

Examples of freshwater include rivers and spring
